I think with my VAR truing stand setup as above, I was getting variation with the radial runout from a spoke hole to the point between spokes to the next spoke hole, so it was impossible to get it "perfect". My machine would only run the lateral gauge on the right side without flipping the wheel, so I wouldn't really notice if the rim got fatter somewhere.
